Portable. Tube. DAC/Amp.

We handle a ton of audio gear at Apos, but every so often something really catches our attention. The xDuoo XD05T Portable DAC/Amp is one of those rare finds—a portable DAC/amp that uses tubes.

What Sets the XD05T Apart?

Genuine 1960s NOS Vacuum Tubes

While lots of portable DAC/amps rely solely on solid-state technology, the XD05T incorporates authentic miniature vacuum tubes from the 1960s.

Hybrid Circuit Design

The combination of vacuum tubes in the preamp stage and transistors for current amplification creates a great mix of warmth and power. This hybrid approach ensures strong output—up to 1,500mW at 32Ω—without losing the musical tonality that tubes provide.

Extensive Connectivity and Format Support

With support for USB, Bluetooth 5.1, AUX, and SPDIF inputs, along with compatibility for high-res formats including PCM, DSD, and MQA, the XD05T is as versatile as it is powerful.
